Ph.D. in Information Sciences, Tohoku UniversityResearch Contents
I am conducting research on constructing and applying machine learning methods to uncover hidden patterns in data. Specifically, I am working on representation learning techniques that derive useful features for prediction from data. I am also developing methods to detect outliers that significantly differ from overall data trends. Additionally, I collaborate with researchers from various disciplines on applying machine learning to issues in the social sciences and other fields.
Attractive Factors of My Research
I am captivated by the point to freely constructing algorithms related to the mechanisms by which machines learn automatically, using new ideas and approaches. I aim to conduct research that transforms zero into one, without being confined by existing frameworks.
